For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Example

[0044] There is a saying that "the aroma of liquor depends on fermentation, and the aroma depends on distillation", which shows that fermentation and distillation are two very important links in the process of making liquor. Before fermentation, the grain needs to be boiled and saccharified, and distillation requires condensation and cooling of the wine vapor. Currently, the existing winemaking machines on the market can achieve the boiling, fermentation and distillation processes, but the cooling process requires manual participation. The grain in the pot needs to be transferred to a larger dustpan or table in the room for air cooling and mixing, resulting in the heat loss of the cooked high-temperature grain cannot be recycled.

[0045] To this end, the present embodiment provides a wine-making machine that can recycle the heat of the high-temperature grains cooked during the wine-making process, thereby achieving good energy-saving effects.

[0046] In one embodiment, if Figure 1 and Figure 2 As shown, the brewing machine includes a fermentation pot 1, a heating structure, a first storage tank 4, a first heat exchange pipeline 5, and a second heat exchange pipeline 8. The fermentation pot 1 includes an inner pot body 101 and an outer pot body 102, and an interlayer 103 is formed between the outer pot body 102 and the inner pot body 101, and the interlayer 103 has a first inlet 1031 and a first outlet 1032; the heating structure is used to heat the fermentation pot 1; the first storage tank 4 is suitable for storing low-temperature water, and the first storage tank 4 has a first water outlet 401 and a first water return port 402; one end of the first heat exchange pipeline 5 is connected to the first water outlet 401, and the other end is connected to the first inlet 1031, and the first heat exchange pipeline 5 is provided with a first water pump 6 and a first valve 7; one end of the second heat exchange pipeline 8 is connected to the first outlet 1032, and the other end is connected to the first water return port 402.

[0047] In this embodiment, the heating structure heats the fermentation pot 1, and the grain can be placed in the fermentation pot 1 to cook the grain. After the cooking is completed, the grain needs to be cooled. At this time, the first water pump 6 and the first valve 7 are opened, and the low-temperature water in the first storage tank 4 enters the interlayer 103 formed by the inner pot body 101 and the outer pot body 102 through the first heat exchange pipeline 5. The low-temperature water takes away the heat of the inner pot body 101 and the grain in the interlayer 103, so that the grain can be cooled quickly, avoiding excessive gelatinization of the grain and increasing its viscosity, which is not conducive to stirring and fermentation. At the same time, the water that absorbs heat is recycled to the first storage tank 4 through the second heat exchange pipeline 8 for storage, which can avoid energy loss and save more energy. Compared with the prior art that requires manual transfer of the grain in the pot to a larger indoor dustpan or table for air cooling, it can greatly reduce the workload of manual labor, thereby reducing labor costs.

[0048] It should be noted that when the volume of the first storage tank 4 is large enough and the pre-stored low-temperature water is sufficient, the grain temperature can be reduced to 38° C. required for fermentation. After the grain temperature is reduced to 38° C. by the first storage tank 4, the koji can be added and fermentation can be carried out.

[0049] On the basis of the above-mentioned embodiments, in a preferred embodiment, a first temperature sensor 9 is provided on the first heat exchange pipeline 5, a second temperature sensor 10 is provided on the second heat exchange pipeline 8, and the wine brewing machine further comprises a controller, which is in communication connection with the first water pump 6, the first temperature sensor 9, and the second temperature sensor 10. The controller can control the first water pump 6 and the first valve 7 to close when the temperature detected by the first temperature sensor 9 is consistent with the temperature detected by the second temperature sensor 10. In this embodiment, by providing the first temperature sensor 9 on the first heat exchange pipeline 5 and the second temperature sensor 10 on the second heat exchange pipeline 8, the water temperature before and after heat exchange can be monitored in real time, so that the cooling condition of the fermentation pot 1 during the cooling process can be monitored. When the temperature detected by the first temperature sensor 9 is consistent with the temperature detected by the second temperature sensor 10, it means that the water in the first storage tank 4 can no longer continue to heat exchange and cool the fermentation pot 1. At this time, the first water pump 6 and the first valve 7 are controlled to close, and the water in the first storage tank 4 no longer continues to flow to the interlayer 103.

[0050] On the basis of the above embodiment, in a preferred embodiment, a first flow valve 11 is provided on the first heat exchange pipeline 5, and the controller is in communication connection with the first flow valve 11. In this embodiment, the setting of the first flow valve 11 can control the flow rate of low-temperature water entering the interlayer 103 of the fermentation pot 1, thereby accurately controlling the cooling effect on the grain.

[0051] On the basis of the above-mentioned embodiment, in a preferred embodiment, the first inlet 1031 is arranged at the bottom of the interlayer 103, and the first outlet 1032 is arranged at the top of the interlayer 103. In this embodiment, since the first inlet 1031 is arranged at the bottom of the interlayer 103, and the first outlet 1032 is arranged at the top of the interlayer 103, the low-temperature water in the first storage tank 4 enters through the first inlet 1031 and slowly fills the interlayer 103 before flowing out from the first outlet 1032, which can ensure the cooling effect on the grain. Of course, in other alternative embodiments, the first inlet 1031 can also be arranged at the top of the interlayer 103, and the first outlet 1032 can be arranged at the bottom of the interlayer 103. Obviously, in this case, the water flows faster in the interlayer 103, so the cooling effect on the grain is not good.

[0052] On the basis of the above embodiments, in a preferred embodiment, the interlayer 103 further has a second inlet 1033 and a second outlet 1034, and the brewing machine further includes a second storage tank 12, a third heat exchange pipeline 13, and a fourth heat exchange pipeline 16. The second storage tank 12 is suitable for storing low-temperature water, and the second storage tank 12 has a second water outlet 1201 and a second water return port 1202; one end of the third heat exchange pipeline 13 is connected to the second water outlet 1201, and the other end is connected to the second inlet 1033, and the third heat exchange pipeline 13 is provided with a second water pump 14 and a second valve 15; one end of the fourth heat exchange pipeline 16 is connected to the second outlet 1034, and the other end is connected to the second water return port 1202, and the controller is also connected to the second water pump 14 and the second valve 15 in communication, and the controller can also control the second water pump 14 and the second valve 15 to open when the temperature detected by the first temperature sensor 9 is consistent with the temperature detected by the second temperature sensor 10 and the grain temperature in the fermentation pot has not dropped to a preset value. In this embodiment, by setting the second storage tank 12, when the temperature detected by the first temperature sensor 9 is consistent with the temperature detected by the second temperature sensor 10 and the grain temperature in the fermentation pot has not dropped to the preset value (38°C), Figure 3 As shown, the second water pump 14 and the second valve 15 are controlled to be opened, and the low-temperature water in the second storage tank 12 enters the interlayer 103 through the third heat exchange pipeline 13. The low-temperature water takes away the heat of the inner pot body 101 and the grain in the interlayer 103, and continues to cool the grain in the inner pot. At the same time, the water that absorbs heat is recovered to the second storage tank 12 through the fourth heat exchange pipeline 16.

[0053] On the basis of the above-mentioned embodiments, in a preferred embodiment, a third temperature sensor 17 is provided on the third heat exchange pipeline 13, and a fourth temperature sensor 18 is provided on the fourth heat exchange pipeline 16. The controller is in communication connection with the third temperature sensor 17 and the fourth temperature sensor 18. The controller can control the second valve 15 to close when the temperature detected by the third temperature sensor 17 is consistent with the temperature detected by the fourth temperature sensor 18. In this embodiment, by providing the third temperature sensor 17 on the third heat exchange pipeline 13 and the fourth temperature sensor 18 on the fourth heat exchange pipeline 16, the water temperature before and after heat exchange can be monitored in real time, so that the cooling condition of the fermentation pot 1 during the cooling process can be monitored. When the temperature detected by the third temperature sensor 17 is consistent with the temperature detected by the fourth temperature sensor 18, it means that the water in the second storage tank 12 can no longer continue to heat exchange and cool the fermentation pot 1. At this time, the second valve 15 is controlled to close, and the water in the second storage tank 12 no longer continues to flow to the interlayer 103.

[0054] On the basis of the above embodiment, in a preferred embodiment, a second flow valve 19 is provided on the third heat exchange pipeline 13, and the controller is in communication connection with the second flow valve 19. In this embodiment, the setting of the second flow valve 19 can control the flow rate of low-temperature water entering the interlayer 103 of the fermentation pot 1, thereby accurately controlling the cooling effect on the grain.

[0055] On the basis of the above-mentioned embodiment, in a preferred embodiment, the second inlet 1033 is arranged at the bottom of the interlayer 103, and the second outlet 1034 is arranged at the top of the interlayer 103. In this embodiment, since the second inlet 1033 is arranged at the bottom of the interlayer 103, and the second outlet 1034 is arranged at the top of the interlayer 103, the low-temperature water in the second storage tank 12 enters through the second inlet 1033 and slowly fills the interlayer 103 before flowing out from the second outlet 1034, which can ensure the cooling effect on the grain. Of course, in other alternative embodiments, the second inlet 1033 can also be arranged at the top of the interlayer 103, and the second outlet 1034 can be arranged at the bottom of the interlayer 103. Obviously, in this case, the water flows faster in the interlayer 103, so the cooling effect on the grain is not good.

[0056] like Figure 1 As shown, the first inlet 1031 and the second inlet 1033 are symmetrically arranged about the central axis of the fermentation pot 1 , and the first outlet 1032 and the second outlet 1034 are symmetrically arranged about the central axis of the fermentation pot 1 .

[0057] On the basis of the above-mentioned embodiment, in a preferred embodiment, the first water pump 6 is arranged at a position close to the first water outlet 401, the first valve 7 is arranged at a position close to the first inlet 1031, the first heat exchange pipeline 5 is connected to the second heat exchange pipeline 8 through the first branch 20, and a third valve 21 is arranged at the connection point between the first branch 20 and the first heat exchange pipeline 5; the second water pump 14 is arranged at a position close to the second water outlet 1201, the second valve 15 is arranged at a position close to the second inlet 1033, the third heat exchange pipeline 13 is connected to the fourth heat exchange pipeline 16 through the second branch 22, and a fourth valve 21 is arranged at the connection point between the second branch 22 and the third heat exchange pipeline 13. Valve 23; the winemaking machine also includes a compressor 24, which is arranged between the first storage tank 4 and the second storage tank 12. One end of the compressor 24 is connected to a refrigeration sleeve 25, and the other end is connected to a heating sleeve 26. The refrigeration sleeve 25 is sleeved outside a portion of the third heat exchange pipeline 13, and the heating sleeve 26 is sleeved outside a portion of the first heat exchange pipeline 5; the controller is communicatively connected with the third valve 21, the fourth valve 23 and the compressor 24, and can control the first water pump 6, the third valve 21, the fourth valve 23 and the compressor 24 to open when the temperature detected by the third temperature sensor 17 is consistent with the temperature detected by the fourth temperature sensor 18 and the grain temperature in the fermentation pot has not dropped to a preset value. In this embodiment, when the temperature detected by the third temperature sensor 17 is consistent with the temperature detected by the fourth temperature sensor 18 and the grain temperature in the fermentation pot has not dropped to a preset value, the second storage tank 12 needs to be cooled before it can continue to cool the grain in the inner pot body 101. Figure 4 As shown, at this time, the first water pump 6, the second water pump 14, the third valve 21, the fourth valve 23 and the compressor 24 are turned on, and the compressor 24 cools the water in the second storage tank 12 through the refrigeration sleeve 25 and continues to cool it to a set temperature. At this time, the water in the first storage tank 4 flows through the heating sleeve 26 under the action of the first water pump 6, and the water in the first storage tank 4 recovers and stores the heat of the heating sleeve 26.

[0058] On the basis of the above-mentioned embodiments, in a preferred embodiment, a pot cover 27 is provided on the top of the fermentation pot 1, and a koji injection module 28 is provided on the pot cover 27. The controller is in communication connection with the koji injection module 28. When the temperature of the grain in the fermentation pot drops to a preset value, the controller can control the koji injection module 28 to inject koji into the fermentation pot 1 and control the first water pump 6, the second water pump 14, the third valve 21, the fourth valve 23 and the compressor 24 to close. In this embodiment, when the temperature of the grain in the inner pot body 101 drops to the temperature required for fermentation, the controller controls the koji injection module 28 to automatically inject koji, thereby realizing automated operation and reducing labor costs.

[0059] On the basis of the above embodiment, in a preferred embodiment, a stirring structure 29 is provided in the fermentation pot 1, and the stirring structure 29 is in communication connection with the controller.

In this embodiment, Figure 7 As shown, when the outside temperature is high and the fermentation yeast generates heat, causing the water temperature of the interlayer 103 to rise and exceed the temperature required for fermentation, the second water pump 14, the fourth valve 23, and the sixth valve 37 are opened, and the low-temperature water in the second storage tank 12 flows to the second heat exchange pipe section through the second water pump 14 and the fourth valve 23, and flows back to the second storage tank 12 through the sixth valve 37 and the fourth heat exchange pipeline 16 after heat exchange in the heat exchange module 33. After heat exchange in the heat exchange module 33, the water temperature of the interlayer 103 gradually drops to the temperature required for fermentation, which can achieve precise temperature control of the fermentation temperature and reduce the energy consumption of the winemaking machine.

[0065] On the basis of the above embodiments, in a preferred embodiment, the third branch 34 and the fourth branch 36 have a common flow pipe section 38, a seventh valve 39 is provided at the intersection of the third branch 34 and the fourth branch 36, and the controller is in communication connection with the seventh valve 39, and the controller can control the seventh valve 39 to open when the temperature detected by the fifth temperature sensor 32 is lower than or higher than the temperature required for fermentation.

Figure 1 As shown, both ends of the flow-through pipe section 38 are three-way heads, and the seventh valve 39 is arranged at the three-way head on the lower side.

[0066] On the basis of the above embodiment, in a preferred embodiment, a wine vapor outlet 2701 is provided on the pot cover 27, and the wine brewing machine also includes a shell and tube heat exchanger 40, the shell and tube heat exchanger 40 has a wine vapor inlet 4001, an alcohol outlet 4002, a hot water inlet 4003, and a hot water outlet 4004, the third heat exchange pipeline 13 is connected to the hot water inlet 4003 through a fifth branch 41, the fourth valve 23 is located at the connection point of the fifth branch 41 and the third heat exchange pipeline 13, the fourth heat exchange pipeline 16 is connected to the hot water outlet 4004 through a sixth branch 42, and the sixth branch 42 is connected to the fourth heat exchange pipeline 16. The eighth valve 43 is provided at the connection point, the wine vapor outlet 2701 is connected to the wine vapor inlet 4001 through the sixth heat exchange pipeline 44, the sixth temperature sensor 45 is provided on the sixth heat exchange pipeline 44, and a wine container 46 is provided at the alcohol outlet 4002. The controller is in communication connection with the sixth temperature sensor 45 and the eighth valve 43. The controller can control the second water pump 14, the fourth valve 23, the sixth valve 37, and the eighth valve 43 to open after the fermentation is completed. The controller can also control the compressor 24 and the first water pump 6 and the third valve 21 to open when the temperature detected by the third temperature sensor 17 is higher than the set temperature. In this embodiment, if Figure 8As shown, when fermentation is over, the winemaker starts distillation, the second water pump 14, the fourth valve 23, the sixth valve 37, and the eighth valve 43 are opened, and the low-temperature water in the second storage tank 12 enters the shell-and-tube heat exchanger 40. When the high-temperature wine vapor reaches the shell-and-tube heat exchanger 40 through the sixth heat exchange pipeline 44, the wine vapor is condensed by the cold and flows to the wine container 46. The distillation process needs to take away a large amount of heat; when the cooling energy of the second storage tank 12 is insufficient, when the temperature detected by the third temperature sensor 17 is higher than the set temperature, the water condensation effect of the second storage tank 12 becomes worse. At this time, the compressor 24 is turned on, the first water pump 6 and the third valve 21 are opened, and the water in the first storage tank 4 absorbs heat through the heating sleeve 26 under the action of the first water pump 6 and continues to store heat. In this embodiment, the second storage tank 12 is used for storing the refrigeration cold of the compressor 24, and the wine vapor is cooled and condensed by indirect internal circulation water cooling and vertical tubes. In the prior art, the compressor 24 and the casing are directly used to refrigerate and condense the wine vapor, and the heat dissipated by the condenser cannot be recycled. The spiral thread in the casing affects the flow of the condensed wine. Therefore, compared with the prior art, this embodiment solves the technical problem that the condensed wine in the threaded tube cannot flow when the casing directly condenses the wine vapor.
